How to Troubleshoot SeaText JavaScript Not Firing on Tilda Pages

If the SeaText script is not firing on your Tilda site, start with the simplest cause: the code was pasted but the page was never saved and published. On Tilda, every edit needs a Publish click before visitors see it. If the page is published and the script still is not running, work through this order: check the placement, check your account and domain, check the browser console, clear cache, and confirm the script URL.

“Not firing” means the script did not execute on the live page, so no SeaText changes appear. In most cases, the cause is a small placement, publishing, domain, or activation mistake.

Before you start: prerequisites

• Have a SeaText account. You need one before you can install the script.
• Copy the JavaScript code from the SEATEXT CODE INTEGRATION section of your account.
• Know which domain you are testing. Each account is linked to a single primary URL.
• Use a real, valid domain. Localhost and dynamic development domains are restricted.
• Test on the published page, not inside the Tilda editor.

Run this diagnostic sequence in order

1. Publish check. Open Tilda and confirm the page or Site Settings was saved and published after the code was added. This is the most common reason the script does not run.
2. Placement check. Verify the code is in the head field or in a T123 block. If it is sitting in another block type, the script may not load where SeaText expects it.
3. Account and domain check. Confirm the SeaText account is active and tied to the domain you are testing. A script from another account or domain will not link.
4. Browser console check. Open Developer Tools, go to the Console tab, and look for red JavaScript errors. Another script error can stop SeaText before it starts.
5. Cache check. Clear the browser or site cache, or open the page in a private window. You may be looking at an old version of the page.
6. Script URL check. Return to your SeaText account and copy the exact script URL again. A broken or outdated URL means the file never loads.
7. Activation check. Visit or refresh the page several times, stay for at least 40 seconds, and wait up to five minutes for the site to connect.

Do not skip the publish step. In many support situations, the fix is as simple as clicking Publish after the paste.

Check your placement: site-wide head or page-specific T123

SeaText gives you two placement paths on Tilda. The first path adds the code to every page.

1. Open your Tilda dashboard.
2. Go to Site Settings.
3. Click More → HTML code for the head section → Edit code.
4. Paste the code into the field labeled “Edit code inside HEAD tag”.
5. Save, then publish your site.

The second path adds the code to one page only.

1. Open the page you want to use.
2. Click the “+” icon to add a new block.
3. Scroll down and choose “Other”.
4. Select the block named T123, which enables embedded HTML code.
5. Open its Content area to access the HTML editor.
6. Paste the SeaText code.
7. Click Save and Close, then click Publish.

Use Site Settings when you want the script on the whole site. Use T123 when you only need it on one landing page or one test page.

Confirm the script is loading in the browser

After publishing, inspect the live page, not the Tilda editor.

1. Open the published URL in a desktop browser.
2. Press F12 or Ctrl+Shift+I to open Developer Tools.
3. Click the Console tab. Fix any red errors. A JavaScript error can prevent later scripts from running.
4. Click the Network tab and look for the SeaText script request. If it is missing, the code was not added or the script URL is wrong.
5. Open the page in a private or incognito window to rule out cached files and browser extensions.

Activate the script and link it to your account

Even with correct placement, SeaText is intentionally inactive until it is activated. That is a security feature, not a bug.

1. Visit your website several times, or refresh it several times.
2. Stay on the page for at least 40 seconds. This activates the AI and links it to your account.
3. Wait at least five minutes.
4. Check the top of the SeaText page for your website name next to the SEATEXT logo.

When the website name appears, the connection is ready. If it never appears, repeat the visits and refreshes, then check that the account domain matches the site URL.

What “not firing” means and when this guide applies

“Not firing” means the SeaText JavaScript did not run on the published page, so no SeaText changes are visible to visitors. This guide applies to Tilda sites that use the global head field or the T123 block. It does not cover custom server-side JavaScript setups, because SeaText is a browser script designed for the published page.

Understanding the difference between “not installed”, “not published”, and “not activated” matters. If you skip the activation step, the script can be on the page and still appear to do nothing. If you skip the domain check, the script can load but never link to your account.

Limitations and edge cases to know

• One account per domain. Each SeaText AI account is linked to a single primary URL. For a development domain and a production domain, create separate accounts.
• No localhost. Development URLs such as localhost are restricted for security reasons. Use a valid, real domain.
• Dynamic development domains may fail. SeaText might not reliably associate traffic with your account on dynamic domains.
• Several websites need several accounts. To use SeaText on multiple websites, create one account for each website.
• Activation needs visits or refreshes. The account links after visits or refreshes and at least 40 seconds on the page.

Key facts at a glance

FAQ

1. Why is my SeaText script not firing even after I pasted it into Tilda? The most common cause is that the page was not published after saving. After that, check placement, browser console, cache, script URL, account domain, and activation.
2. How long does SeaText take to activate on Tilda? According to the SeaText Tilda integration, visit or refresh the site several times, stay for at least 40 seconds, then wait at least five minutes for the website name to appear.
3. Can I test the script on localhost? No. Development URLs like localhost are restricted for security reasons. Use a valid, real domain.
4. Do I need a separate SeaText account for each Tilda domain? Yes. Each account is linked to one primary URL, so you need separate accounts for separate domains.
5. Should I use Site Settings or a T123 block? Use Site Settings for the whole site. Use a T123 block when you want the script on one page only.
6. How do I know SeaText is connected to my Tilda site? After activation, your website name appears next to the SEATEXT logo at the top of the SeaText page.
